There's been a steady stream of snacks, candies and other products made with peanut butter pulled off the market since the company at the center of this outbreak, Peanut Corp. of America, expanded its own recall last week to include peanut paste.

That move prompted Oregon officials today to call all food retailers registered with the state, including small mom and pop stores, and warn them about the recall.

Peanut Corp. sells to 77 distributors and manufacturers that turn the paste into hundreds of products.

As federal officials track the sales to Peanut Corp.'s customers and to their customers and on down the line, the recall list will continue to grow, said William E. Keene, senior epidemiologist at Oregon's Public Health Division.

So far, 485 people have been sickened in 43 states and Canada. They include seven people in Oregon, with two and possibly three more cases popping up this month.

At least six deaths, including one in Idaho, have been linked to the outbreak that started in September.
